Domenico Scarlatti
By Ralph Kirkpatrick
Princeton, NY: Princeton University Press
1953
Pg. 308:
The essential expressive quality of a melodic interval lies not in the notes themselves but in the space between the notes, in the manner in which one gets from one note to another. The assumption that musical value lies in the notes themselves and not in the transition from on to another is the prime heresy of the keyboard player.
